L. L. HOSKINSON WATER MOTOR Filed March 4, 1927 2 Sheets-Sheet 2 41011134. f/osn/nson INVENTOR ATTO R N EY WITNESSK Patented Apr. 14, 1931 UNITED" LOUIS L. nosxmson, or c INrroN, IOWA WATER Application filed March 4,

This invention relates to a water motor, the general object of the invention being to provide a wheel with its blades or paddles movably arranged and having their movement limited so that they will resist the movement of the water entering the wheel, but will move with the water leaving the wheel so that the wheel can be operated by a current of water without necessitating the wheel being placed under a waterfall.

Another object of the invention is to provide means for directing the water against the wheel in such a manner as to secure its maximum propelling effect.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view of the apparatus.

Figure 2 is a side view.

Figure 3 is a section on line 3-3 ofFigure 1.

Figure 4 is a section on line 4-4 of Figure 2. v

In these views, A indicates the flum'e form ing casing which has a fiat bottom 1, the flat sides 2 having their front ends diverging, as at 3, and the'top piece formed with a semicircular central portion 4, and upwardly and outwardly inclined end pieces 5 and 5, the front end piece 5 having its edges diverging to fit the diverging parts 3 of the side pieces and the rear end piece 5 being of less length than the rear part of the casing. The front part is provided with a false floor 1 which extends upwardly and inwardly at an angle and forms with the part 5 and the parts 3 a gradually decreasing mouth or inlet at the front end of the casing for directing the water entering the same against the wheel B in the central part of the casing. This wheel com rises the end pieces 6 which are fastened to t e horizontal shaft 7 which is journaled MOTOR 1927. Serial No. 172,901.

in the side pieces of the casing and the blades 8 which are pivotally secured to the end pieces through means of the rods 9 which are arran ed in an annular row adjacent the shaft An outer row of rods 10 is carried by the end pieces 6, the row being arranged adjacent the periphery of the wheel and these rods act as stops for limiting the movement of the blades. As will be seen, the wheel extends into thespace formed by the part 4 of the top of the casing and the central extension of the side pieces thereof.

I provide the wheel with an odd number of blades or paddles, the drawings showing the wheel provided with seven blades. Of 6 course, it is to be understood that I do not wish to be limited to this number. By providing an odd number, the blades in the lower part of the wheel will lie closer together than the blades in the upper part of the wheel.

As will be seen from Figure 3, the water entering the mouth of the casing will be directed against the blades moving downwardly with the wheel so that the pressure eX- erted by the current of water will operate against the blades, forcing them against the bars 10 and thus rotating the wheel. When the blade moves to a position where it is acted on by the water leaving the wheel, it will as- P sume a horizontal position so as to offer no resistance to the passage of this water and it will finally drop back upon the next rod 10 from the one which it had been previously engaging so that the blade will be carried upor wardly until it reaches a vertical position at the top of the wheel, when it will drop forwardly, as soon as it starts on its downward movement, until it strikes the rod 10 in front of it.

From the foregoing it will be seen that with this wheel composed of the movable blades, the device can be placed in streams of water which have but little current and it is not necessary to build dams or the like to create a waterfall or a swift current to operate the device. Thus this apparatus can be used in level countries and the improved wheel will secure the maximum amount of power from a slow current.

Power can be taken from the wheel such as by mounting a shaft 1l on the supports 12 7 and belting or otherwise connectingit With 7 i the shaft 7, this shaftll being adapted to be cennected to a, device to be driven." i It is thought from the foregoing description that theadvantages and novel features Q of myjinventiOnwvillbe readily-apparent); Y e Itdesir'e'itto beunderstood thatlrnay make. changes in the'constr uction andjin the f c0m=- n i and a g nt 9f f 'parts,'previded that such" changesfaill'with in the scope of the appended claim. v v r 'WhatI c1aim'is:" r V v r A Water motor mp ising ie sas nghavinga an inlet at its front end composed of con vergentuppe and Jewels wallseandjcenvetgent side W ll s id' vaesingahayi g fia 'bqtte i: Y theifolzward par Of which extndsnndl fllfi law r: Wall Qf hevinlet, there ri nd nten- 7 medieteparts oi he ae i' g ha ing s raightside 7 W lls; a su stantial y semi-eircu as .top' wallat-thebenterof th -Qasingthe frontedg'e ofwhi h is. connected?
